Drop in CO2 heralded the onset of Antarctic glaciation

For about 100 million years all sorts of animals roamed the then subtropical North and South poles. But then suddenly some 34 million years ago during the Eocene everything changed when temperatures fell dramatically in only a 100,000 year timespan, … Continue reading

Marine biodiversity driven by environmental changes

Our most important source for knowledge about past life is the fossil record. But how exact is it in telling us about the history of life? According to a new study in Science the evolution of marine life over the … Continue reading

Good news? According to paleo research median CO2 climate sensitivity could be 0.7 degrees lower

The most-quoted climate sensitivity range (IPCC 4AR) suggests a median temperature response to a doubling of the atmospheric CO2 concentration of 3 degrees Celsius – and a 66 percent probability range warming under CO2-doubling will be somewhere between 1.5 and … Continue reading

Amphibians in more trouble than previously thought

Climate change, land-use change and the fungal disease chytridiomycosis. Those are the main causes why more than 30 per cent of all amphibian species have appeared on the Red List of the International Union for the Conservation of Nature (IUCN). … Continue reading

Holocene climatic changes were local phenomena – except current warming

Of course you know these people that by now feel a bit cornered and say ‘okay, perhaps temperatures are going up. But that’s what it does, the global climate changes all the time.’ Well, to keep things simple: no, it … Continue reading

World average land temperatures have risen by almost 1 degree since 1955 – says 4th consecutive study

Whom would you rather believe? The world’s three best-established atmospheric research institutes – or a Berkeley dream team with the current Physics Nobel Prize laureate, backed up by the largest collection of land temperature measurements ever? So sorry to confuse … Continue reading
